2. Read the paragraph carefully and answer the following carefully
Compounds composed of metals and non-metals contain charged species The charged
species are known as ions. An ion is a charged particle and can be negatively or positively
charged. A negatively charged ion is called 'anion' and positively charged called 'cation. In
sodium chloride [ NaCij, the constituent particles are positively charged sodium ions/Na'
and negatively charged chloride ions (Cl" ]. Ions may consist of a single charged atom or a
group of atoms that have a net charge on them. A group of atoms carrying a charge is known
as a polyatomic ion.
(1) What are called ions?
(in) Name the negatively charged species.
(iii) In NaCl which is anion and cation?
(iv) What we called if the ions consists of group of atoms and have net charge on
